It's day two with my new LG OLED55C8 and I've noticed a really annoying vertical banding has appeared. Didn't seem to be there on day one but now exists - nothing has changed between turning the TV off yesterday and turning it on again today.

Is this a faulty panel? Or is it something that will go away? It appears on all sources and is quite noticeable.

Should I be taking it back?

Yes. As a first step maybe show the store the picture posted above. Day Two is as good as DOA in my book.
Is the banding there on all inputs?

I've only tried on two inputs but it's there on both. The source doesn't seem to make a difference either (Sky, Roku, Xbox, TV Apps). Have read elsewhere that needs about 100/200hrs for the screen to "bed in" and that there are compression cycles the TV runs after a few hours use. Like you've suggested, I might take the images in to Smith's City and show them so they are aware I could be bringing it in to be swapped.

I would not be happy to have to look at that at any time.

I always call BS on things needing to wear in etc. Its time to allow you to get used to things, or for the DOA return period to expire. Speakers/headphones are a terrible one where they claim they need to "wear in" and I would hate to see that carry on try to be applied to screens.

That is unwatchable like that, you paid for a watchable screen so get onto the retailer about it being a dud and you consider that a serious issue with it needing to be resolved.

We have the identical model (now 2-3 months old) and nothing remotely like that. As the others have said above, it’s definitely not right - report &/or take it back ASAP.

Sometimes I just sit and think. Other times I just sit.

2 days old = replacement in my book.

Was prepared to give it a day or two to see what happened but it started bugging me too much so took it back and have a replacement now. Fingers crossed this one is the real deal. Thanks for all your suggestions / feedback.

Let us know how it goes. Once you get it sorted, you won’t regret the purchase - it’s a great TV.

@NzVanFan How did you get on with the replacement TV?

Took it back the day of that post and got a replacement. Despite showing video and photos of the banding they made me turn it on in the store as well (probably more to do with the fact I got the TV due to a pricing error I suspect).

Anyway, got a replacement TV and it's like a different machine. This one has none of the previous issues and is fantastic. Really enjoying the TV so far. Will wait a couple of weeks before I start playing around with the settings so I know what aspects of the image I want to change.

Glad to hear things have worked out.
When you do decide to play around with settings the are a couple of YouTube sites that are worth a look.

Vertical banding is an incredibly common problem with all OLEDs and you're doing very well if it doesn't have any at all.

That being said, it is generally not noticeable during normal content and yours looked horrendously bad, so I think a replacement was more than warranted and I'm glad the replacement is a lot better.

Mine has a little (but nothing like that) but from what I have read it is a bit of a lottery and often a replacement is worse so I decided to leave it and see if I notice it during normal content. I'd say 98% of the time I can't see it no matter how hard I look, and the other 2% I have to be specifically looking for it to spot it.

If you used the TV for longer than 4 hours on day one, then it ran it's first compensation cycle when you turned it off. The compensation cycles are meant to improve the overall picture, but it's not unheard of for it to sometimes make banding worse.
